<p>Method of making an oleophobic layer 20 on a fluoropolymer 10 comprising the steps of forming an aqueous oleophobic treatment composition by mixing solvent, water and a fluoroalkyl acrylate copolymer, casting the aqueous oleophobic treatment composition onto the fluoropolymer 10, and drying and curing the treatment composition. The fluoropolymer 10 may be a porous membrane comprising expanded polytetrafluoroethylene (ePTFE). The solvent may be an alcohol based solvent. Also specified are coated articles comprising a fluoropolymer, and an oleophobic layer comprising a fluoroalkyl acrylate copolymer in direct contact with the substrate.</p> |
